All the people are cultivating immortality: I can fast forward infinitely

Yan Chenghong seemed to be still immersed in shock and did not hear anyone else's comments.

His expression was quite serious. After a moment of silence, he returned the jade bottle to Lin Feng.

Lin Feng did not reach out to take it, but simply said: "If the head of the Yan family can agree to my unkind request, there is no harm in giving this spirit-gathering pill to the Yan family."

Yan Chenghong's hand holding the warm jade bottle unconsciously closed.

Those deep and wise eyes looked at Lin Feng again.

Lin Feng looked calm and unmoving.

Yan Chenghong was silent, then handed the jade bottle to Yan Shisan, "Let your second uncle draft the contract."

The content of the contract is naturally what Lin Feng said before——

He asked to enter the Yan family's Sutra Collection Pavilion in advance. As a price, he would refine the top-quality foundation-building pill for the Yan family.

Of course, if he fails to refine the ultimate foundation-building pill in the end.

In the next five years, he will refine one hundred perfect spirit-gathering pills for the Yan family every month as compensation!

The Yan family works very efficiently and the contract was signed quickly.

After it took effect, Yan Chenghong took Lin Feng to the Yanjia Scripture Collection Pavilion.

The Yanjia Sutra Pavilion is much grander than the library of Qingcheng No. [-] Middle School.

I don’t know how many years ago it was built, but the style is quite old and has a charm of vicissitudes of life.

Various formations are set up in the Sutra Pavilion.

Lin Feng was led in by Yan Chenghong.

Afterwards, Yan Chenghong gave him a jade tablet: "Stay for up to two hours and choose a jade slip of magic."

Lin Feng nodded, took the jade token and started walking around the Scripture Collection Pavilion.

The jade slips in the Sutra Pavilion seem to have some kind of barrier.

The jade token in his hand is the key to breaking through those barriers.

This time, because the goal was not clear enough, Lin Feng spent a lot of time shopping.

More than an hour passed, but I still couldn't find a spell I was particularly satisfied with.

After all, what he wants is a spell that can be used during the Qi refining period and even help him to leapfrog and build a foundation.

And the spells in this Sutra Pavilion are quite high-end.

But either it is so powerful that it cannot be used during the Qi refining period.

Either it can be used during the Qi refining period, but its power will be greatly reduced.

And there were so many spells in this Scripture-Depository Pavilion that he couldn't even visit a tenth of them in two hours.

Later, Lin Feng simply stopped taking out the jade slips one by one and checking them.

Just looking at the name of the spell, I thought it looked interesting, so I took it out to check the specific content.

Just like that, at the end of the two hours, he actually selected a book called "Nine Sounds of the Ghost", a sound-killing spell!

The name of this spell seems pretty cool.

Lin Feng originally didn't want to take it out and take a closer look.

But the word "nine" hit him.

Monks have their own specialties.

The number "nine" represents "pole".

Generally speaking, if you dare to name a spell with this number, it means that the person who created this spell is probably quite crazy.

After taking down the content and checking it, I found that this spell is indeed very powerful.

But it’s also quite tricky…

Generally, sound-killing spells are used with musical instruments.

But "Nine Sounds of Ghost Ghost" is similar to "Lion's Roar" and does not require matching instruments.

Instead, it is the monk's body that speaks.

And unlike "Lion's Roar", the pronunciation of "Nine Sounds of Ghost Ghost" is not simply pronounced with the throat.

Instead, use the monk's entire body!

The throat, nasal cavity, lower abdomen, and even the internal organs all coordinate with the pronunciation!

When one reaches a high level of training, the monk's muscles, bones, and even ligaments must all work together to pronounce the words together!

This trait alone requires monks to have strong physical fitness.

To put it simply, it is best to practice martial arts.

If that's all, this spell isn't too tricky.

The issue is……

This spell also has a fatal drawback——

When this sound killing technique is used, there will be no distinction between friend and foe!

In other words, monks must not only have strong physical fitness to perform this sound killing technique.

You need to have stronger physical fitness to withstand this sound killing technique!

Damn it!

But this deceptive spell is not without merit.

At least in the golden elixir stage, you can use it to build the foundation stage, and you can easily kill a large area in minutes.

During the foundation building stage, use it to refine the Qi stage, and you can get a large amount of it every minute and every second.

Yes, that's right.

Other spells help monks improve their combat power in battles at the same level or even across levels.

This spell provides convenience for the monks to frighten Xiao Xiao.

It can be said to be very considerate.

When Lin Feng chose it, he was quite hesitant.

But this special sound-killing technique produced by the body really attracted him.

In addition, when he was refining his body, he destroyed an entire mine!

With such physical fitness, if he didn't practice some spells that required high physical fitness, Lin Feng would feel sorry for the spiritual crystal that was destroyed by him.

In addition, he really didn't have much time to continue choosing spells.

So, this is the book "Nine Sounds of Ghost Ghost"!

After that, he took the jade slip to register for re-engraving just like he did in the school library before.

As the head of the family, Yan Chenghong naturally knew what spell Lin Feng had chosen.

Hearing that Lin Feng chose "Nine Sounds of the Underworld", he frowned subconsciously, but didn't say much.

After all, Lin Feng is not from his Yan family.

What spell he chooses is his own business.

After selecting the spell and before entering the alchemy room, Yan Chenghong handed Lin Feng the Sumeru Ring containing three top-quality foundation-building elixir ingredients.

After Lin Feng took the ring, he did not enter the alchemy room immediately. Instead, he said to Yan Chenghong: "I have a small request, which I hope the head of the Yan family can agree to."

When Yan Chenghong heard this, he felt something bad in his heart.

Fortunately, Lin Feng's request was not too excessive: "I also want a foundation-building elixir material of ordinary quality and a foundation-building elixir recipe."

Yan Chenghong stared: "You want these..."

Lin Feng had already thought of an excuse: "Master Yan should also be able to guess that I have a very powerful alchemy master in the world of immortal cultivation. Previously, I used the prescriptions provided by the master to refine the best foundation-building pills."

"As for Xuan Shuixing's foundation-building elixir recipe, I haven't seen it yet."

"I want a copy of the elixir room because I want to compare it with my master's elixir recipe."

"I want an ordinary foundation building material because I want to practice briefly before using those high-quality materials."

This reason was perfect, and Yan Chenghong agreed after thinking about it.

But in fact, Lin Feng did not have any foundation-building elixir recipe at all.

As for ordinary Foundation Building Pill materials...

What he was thinking was that with his high-grade spirit stones and fast-forwarding golden fingers, he might not need high-end materials at all for a mere top-grade foundation-building pill!

There's no telling, he can make the best foundation-building pill using ordinary materials.

And using high-end materials, if what you directly refine is the Perfect Foundation Establishment Pill...

Where can he get the best foundation-building pill?

Give the Perfect Foundation Establishment Pill to the Yan family?

Although the Yan family treats him pretty well.

But Lin Feng didn't want to give someone free sex like this.

So, there are four materials in total.

Refining the best foundation-building elixir from ordinary materials;

High-end materials are used to refine the perfect foundation-building elixir.

Anyway, he will use the Perfect Foundation Establishment Pill to build his foundation in the future.

and……

About building the foundation for your future.

Lin Feng had a rather bold idea in his mind.
